    Tankless Water Heater Maintenance

    Maintenance intervals and procedures come from the exact model manual and local water conditions.

    Direct answer

    Inspect and clean the inlet filter, check venting and drains where applicable, and descale only by the method and interval specified by the manufacturer. Hard water may require more frequent service or treatment.

    Follow the model manual

    Valve positions, approved fluids and service sequences differ. Preserve warranty records and do not copy a procedure from another model.

    Water quality

    Scale risk rises with hardness and operating conditions. Testing the water provides a better service plan than a universal interval.

    Does every tankless heater need annual descaling?

    Not necessarily. Follow the manufacturer interval and adjust for measured water quality and observed scale.
